Toyota and Lexus security key: will openpilot work?
Some newer Toyotas work after a key is read from the car; others cannot run openpilot yet, and the page lists both.
You need
- Your car's model, year and trim
- Willingness to read a long technical page
- A comma device only after the page says your car works
In plain words
Why this guide matters
Since 2021, Toyota and Lexus have signed their steering messages with a security key, blocking openpilot on many cars. This community page tracks which cars have had the key read and work, which are being tried, and which cannot. Read it before buying a comma four for a newer RAV4, Camry, Sienna or Lexus.
